摘要
为了提高矿井高温区域降温效果,研究大焓差集中降温空调热力学机理及大温降小温差换热技术等内容,通过创新研究建立井上制冷输冷至采区进风巷口集中降温的矿井降温系统设计理论和方法,并以传热传质、空气动力学、热质交换原理为理论基础,提出采区大焓差可控风阻的集中降温技术,使用喷淋式降温除湿空调。结果表明,降温后采区进风巷、工作面、总回风巷内舒适温度分别降低了7.0、5.2和4.0℃,解决了矿井因地温高造成工作环境温度高、湿度大的难题。
In order to improve the cooling effect in the high-temperature area of mines,the thermodynamic mechanism of large enthalpy difference centralized cooling air conditioner and the heat exchange of large temperature and small temperature difference were studied.The design theory of mine cooling system was to establish the centralized cooling from the cooling transport in the mine to the air inlet of the mining area through innovative research,and based on the principles of heat and mass transfer,aerodynamics,and heat-mass exchange,a concentrated method for controlled wind resistance with large enthalpy difference in the mining area was proposed.Cooling technology,with spray cooling and dehumidifying air conditioning,the results showed that after cooling,the comfortable temperature in the air inlet roadway,working face and general return roadway of the mining area was reduced by 7.0,5.2 and 4.0°C respectively,which solved the problem of high working environment temperature and humidity in mines caused by high ground temperature.
